I think it is this way at present, simply because the internet allows anyone to say pretty much anything, about any subject, and in no time at all, their message is sent all around the globe, drawing like-minded believers.
One guy, on a bet, and for a thesis, decided to make a movement to get diapers placed on any and all animals the public has to see, in order to cover up their privates. He had quite a few followers.
There is also the Brit whose last name is NORMAN who said he could write a series of books that are completely misogynistic about women being in slavery in an alternative universe, and he did indeed drawn an international following. It was the "GORE" series. To this day, in the BDSM community, there are GOREANS that try and emulate that society as much as they can. There are even a few GOREAN communes in the way back in some states and countries.
So the internet makes it possible to spread all these wild-assed theories, and because there are so many of them out their, no one really believes much of them any more.
Some could be 100% completely true, but it is hard to find a yummy tootsie roll hidden in a pile of bullcrap.
